摘要： To provide an accelerator system having a wide ion beam current control range, being capable of operating with low power consumption and a long maintenance interval and being capable of preventing unnecessarily large dose of the ion beam for irradiation from erroneously being supplied to the downstream side of the system. In an accelerator system designed to treat the patient with irradiation of a high-energy ion beam accelerated by a post-accelerator 4 comprising a synchrotron in irradiation rooms 6 to 8, a value of ion beam current to be supplied to the post-accelerator 4 is controlled by a pre-accelerator comprising an ion source 10, quadrupole electromagnet 15, radio frequency quadrupole accelerator 17 and a drift tube type accelerator 19. The accelerator system featuring low power consumption, a long maintenance interval and high reliability can be made available.
